1. An apparatus, comprising:
- an acoustic sensor;
a controller arranged to analyze an output of the acoustic sensor and to output a signal indicating a predefined state based on the analysis;
a molded package enclosing and integral to the acoustic sensor and the controller, the package including a cavity surrounding at least the acoustic sensor; and
a transducer component within the cavity, the transducer component contacting a protective membrane of the acoustic sensor and conducting acoustic waveforms from the membrane to the acoustic sensor.

Abstract
Representative implementations of devices and techniques provide an improved signal receive time to a sensor component. The sensor component is enclosed within a package arranged to allow the sensor to potentially receive a signal in less time. The package may have a cavity, and the cavity may be at least partly filled with an acoustical transducer.
